Ma. Verheijen et al., OPTICAL AND ATOMIC-FORCE MICROSCOPY STUDIES OF RHOMBOHEDRAL DOMAINS IN C-70 CRYSTALS, Philosophical magazine. A. Physics of condensed matter. Defects and mechanical properties, 72(5), 1995, pp. 1141-1159
On the {100} and {111} surfaces of C-70 crystals the phase transition
of the f.c.c. structure towards the trigonal structure has been studie
d in situ with the help of optical reflection microscopy. Extensive ex
situ studies of domain patterns on both types of surface have been pe
rformed using both optical and atomic force microscopy. A detailed int
erpretation of the domain patterns is given. An additional phase trans
ition was observed in situ at 303 K.
